Component Specifications

Definition
A conductive element is the core component of biopotential electrodes, designed to establish stable electrical contact with biological tissues (skin, muscle, nerve) to capture and transmit weak bioelectrical signals (ECG, EEG, EMG) to amplification and recording systems with minimal noise and impedance.
Working Principle
Works by creating an ionic-to-electronic current conversion interface: ions from biological tissues interact with the conductive surface, generating electrical currents that are transmitted through the element to monitoring equipment, facilitated by electrode gels or direct contact to reduce skin impedance.
Materials
Silver/silver chloride (Ag/AgCl) for high conductivity and stability, stainless steel for durability, conductive polymers (PEDOT:PSS) for flexibility, or gold-plated surfaces for low-noise applications.
Technical Parameters
  • Size Diameter 5-30 mm
  • Lifespan >1000 uses
  • Impedance <5 kΩ at 10 Hz
  • Noise Level <1 μV RMS
  • Frequency Response 0.05-10,000 Hz
Standards
ISO 10993-5, ISO 13485, DIN EN 60601-2-25
